We offer our heartfelt thanks to the many stakeholders that are making our vision for Best Practice Guidelines (BPG) a reality: the Government of Ontario, for recognizing RNAO’s ability to lead the program and for providing multi-year funding; Drs. Irmajean Bajnok and Monique Lloyd, Director and Associate Director (respectively) of the RNAO International Affairs and Best Practice Guidelines (IABPG) Centre, for their expertise and leadership in advancing the development of BPGs; and Expert Panel Chair Laura Teague, Wound Specialist at Saint Michael’s Hospital in Toronto, Canada, for her exquisite expertise and stewardship of this guideline.

Special thanks to the entire BPG Expert Panel for generously providing time and expertise to deliver a rigorous and robust clinical resource. We couldn’t have done it without you! The nursing and health-care community, with their unwavering commitment and passion for excellence in patient care, have provided the expertise and countless hours of volunteer work essential to the development and revision of each guideline. Employers have responded enthusiastically by nominating best practice Champions, implementing guidelines, and evaluating their impact on patients and organizations. Governments at home and abroad have joined in this journey. Together, we are building a culture of evidence-based practice. Successful uptake of BPGs requires a concerted effort from educators, clinicians, employers, policy makers and researchers. After lodging the evidence into their minds and hearts, knowledgeable and skillful health professionals and students need healthy work environments to enable guideline use and practice changes. We ask that you share this guideline with members of the interprofessional team, as there is much to learn from one another. Together, we must ensure that the public receives the best possible care every time they come in contact with us – making them the real winners in this important effort! Doris Grinspun, RN, MSN, PhD, LLD (Hon), O. ONT. Chief Executive Officer Registered Nurses’ Association of Ontario 2 REGISTERED NURSES’ ASSOCIATION OF ONTARIO Assessment and Management of Foot Ulcers for People with Diabetes, Second Edition Greetings from Vasanthi Srinivasan and Susan Williams, Lead ADMs, Council of the Federation, Clinical Practice Guidelines Working Group At their Council of the Federation meeting in January 2012, provincial and territorial Premiers launched a series of new initiatives designed to encourage collaboration and cooperation on health care innovations across the country. Premiers received the first report from the Health Care Innovation Working Group co-chaired by PEI Premier Ghiz and Saskatchewan Premier Brad, and directed their Ministers of Health to come together and work closely with national and regional health professional organizations to ensure that Vasanthi Srinivasan Susan Williams Canadians have access to the best quality health care in the world. While Premiers acknowledged that Canada’s provinces and territories are pursuing innovation in their own jurisdictions, they recognized that more transformative, lasting change can be achieved together. As part of this new initiative, Premiers asked Ontario and Alberta to co-lead work on accelerating the adoption of key clinical best practice guidelines across the country. Premiers want to ensure that all Canadians benefit from up to date, evidence-based guidance, regardless of where in Canada it is developed. So, after consulting with government health officials, major health professional groups including CMA, CNA/RNAO, HEAL, and many other relevant experts, provincial and territorial Ministers of Health recommended to their Premiers the wide adoption of two guidelines for the initial phase of this pan-Canadian work. One of these two guidelines was the Registered Nurses’ Association of Ontario (RNAO) Assessment and Management of Foot Ulcers for People with Diabetes. Ensuring quality health care requires access to high-quality, regularly updated advice for patient care. The RNAO’s Nursing Best Practice Guidelines Program provides Premiers with exactly the level of scientific rigour they are looking for, combined with the accessibility and usability needed to quickly spread the guideline to nursing practitioners and other health professionals across the country. Given Canada’s aging population and rising rates of diabetes, our health systems will increasingly depend on resources like the RNAO’s Assessment and Management of Foot Ulcers for People with Diabetes guideline to manage demands for these important health care services. We would like to thank RNAO for their hard work and leadership in transforming evidence into action. This ongoing commitment is helping to ensure quality health care for all Canadians.
